i have the hyper grounding system, but thats just the grounding wires. anyway i noticed a pretty good difference and its only $125 w/ shipping from www.newtoyotaparts.com. looks like the hyper voltage system is only $118 from the same site, not sure on shipping.
Installation is a little tricky. Instruction says to simply replace the Ignition Fuse with the one supplied with the Raizin and another connect to ground. Simple enuf right? Not quite. I located one called ECU IG 15A and another IGN 5A. So which one? Turned out to be neither. But after a long time examining the wires to the ignition coil and the wires at the ECU, (mine has 2 coil packs and 4 wires leading to each coil pack), there is a 12v supply to each coil pack and also a 5v supply to each coil pack. The IGN 5A fuse connects to the 5v supply of the coil packs. Cant be this fuse right? The instructions says to connect to the 12v supply. Ideally, I should be using 2 Spark Type S to connect to each 12v supply for each coil pack. But Im not prepared to spend more $$$ on something Im not sure whether will work. So finally found a 30A AM2 fuse in the engine bay that controlled all IGN fuses, both the 12v and 5v, and also the ST fuses, like gauges, instruments, fuel injection, and SRS. The one that came with the Raizin Spark is a 15A one and not good to replace a 30A one with a 15A one, but it was the next best one to choose. Here are some pics:
Conclusion: Did i notice any preformace boost? Nope. In fact my first 0~100kph test showed it was SLOWER. My second test showed it was the same. Is it smoother at idle? Not really. In fact it appears to be less smooth at idle! I have half a mind to remove this useless device. I will try to do more tests first before I jump to conclusions. I will try hooking up to the IGN 5A fuse controlling the 5v supply to the coil packs. Also maybe try the ECU IG 15A fuse, even though it has no relation to the power supply to the coil packs. If Im feeling really adventurous I might buy another Raizin Spark S and connect to each of the 12v coil pack supply. But do I really want to waste more money on a BS product? :bullshitz
I decided to look for a better location to tap the Raizin Spark into. Tapping into the AM2 30A fuse just didnt seem right to share with the 'IGN' and 'ST' devices. I tried the ECU_IG 15A fuse and the IGN 5A fuse but didnt seem to make any difference in performance. The raizin manual says that most toyotas tap into the IG2 fuse. But my camry doesnt have an IG2 fuse. But my 2AZ-FE Ipsum and Corolla do have an IG2 fuse. Weird. So I decided to look at my haynes electrical wiring diagram and true enuf, there is no IG2 fuse. But instead IG2 is located very near the ignition switch. So I have to hunt for this connection point. Gen4 camry Ignition System Wiring diagram here:
The IG2 powers both the 12v supply +B and the 5v supply IGF to the coil packs, so it is definately the ideal point to tap. And the raisin spark is not shared with any other devices except the ignition system. Kind of selfish if you ask me, but that's what this product is all about, dedicated VS for the ignition system alone. Here is a pic of the wire tap (yellow wire):
And here's a cosy corner I found for it under my dash:
This product is very easy to install if you have a newer Toyota with IG2 fuse. Otherwise do what I do if you have an older Toyota with no IG2 fuse. Here is the Raizin Spark Type S installation manual for those of you interested to try this product:
Good Lord what piece of crap that is. The battery is what stabilizes the electrical system. An alternator provides a slight rippling DC current, and the battery is what provides a stable current to the whole system.
Technically, a car could only start with the battery, and once it's charged you could disconnect the battery and let the car run off the alternator but.......that's why the battery is there to regulate system voltage, it absorbs the minor amount of DC ripple off the battery.
A starter can pull a couple hundred amps while cranking, which is the batteries job. Do you really think running all the electrical stuff on your car is really going to tax the electrical system that hard to equal the starter? i.e. with battery and alternator combined? nope
